The debate about how much and how fast to cut the deficit has often been presented as a replaying of the debates of the 1920s and 30s between Keynes and the Treasury.
The justification for fiscal expansion to tackle the recession in 2008/9 was portrayed as classic Keynesianism. The problem was seen as a short-term one of a lack of spending. The solution was seen as one of expansionary fiscal and monetary policies. There was relatively little resistance to such stimulus packages at the time, although some warned against the inevitable growth in public-sector debt.
But now that the world economy is in recovery mode – albeit a highly faltering one in many countries – and given the huge overhang of government deficits and debts, what would Keynes advocate now? Here there is considerable disagreement.
Vince Cable, the UK Business Secretary, argues that Keynes would have supported the deficit reduction plans of the Coalition government. He would still have stressed the importance of aggregate demand, but would have argued that investor and consumer confidence, which are vital preconditions for maintaining private-sector demand, are best maintained by a credible plan to reduce the deficit. What is more, inflows of capital are again best encouraged by fiscal rectitude. As he argued in the New Statesman article below
One plausible explanation, from Olivier Blanchard of the IMF, is that the Keynesian model of fiscal policy works well enough in most conditions, but not when there is a fiscal crisis. In those circumstances, households and businesses react to increased deficits by saving more, because they expect spending cuts and tax increases in the future. At a time like this, fiscal multipliers decline and turn negative. Conversely, firm action to reduce deficits provides reassurance to spend and invest. Such arguments are sometimes described as “Ricardian equivalence” – that deficits cannot stimulate demand because of expected future tax increases.
Those on the other side are not arguing against a long-term reduction in government deficits, but rather that the speed and magnitude of cuts should depend on the state of the economy. Too much cutting and too fast would cause a reduction in aggregate demand and a consequent reduction in output. This would undermine confidence, not strengthen it. Critics of the Coalition government’s policy point to the fragile nature of the recovery and the historically low levels of consumer confidence

Questions
- What factors in the current economic environment affect the level of consumer confidence?
- What are the most important factors that will determine whether or not a policy of fiscal consolidation will drive the economy back into recession?
- How expansionary is monetary policy at the moment? Is it enough simply to answer this question by reference to central bank repo rates?
- What degree of crowding out would be likely to result from an expansionary fiscal policy in the current economic environment? If confidence is adversely affected by expansionary fiscal policy, would this represent a form of crowding out?
- Why may fiscal multipliers have ‘turned negative’?
- For what reasons might a tight fiscal policy lead to an increase in aggregate demand?
- Your turn: what would Keynes have done in the current macroeconomic environment?
With an election approaching, there is much debate about recovery and cuts and about the relationships between the two. Will rapid cuts stimulate confidence in the UK by business and bankers and thereby stimulate investment and recovery, or will they drive the economy back into recession? The debate is not just between politicians vying for your vote; economists too are debating the issue. Many are taking to letter writing.
In the February 2010 news blog, A clash of ideas – what to do about the deficit, we considered three letters written by economists (linked to again below). There has now been a fourth – and doubtless not the last. This latest letter, in the wake of the Budget and the debates about the speed of the cuts, takes a Keynesian line and looks at the sustainability of the recovery – including social and environmental sustainability. It is signed by 34 people, mainly economists.

Questions
- Summarise the arguments for making rapid cuts in the deficit.
- Summarise the arguments for making gradual cuts in the deficit in line with the recovery in private-sector demand.
- Under what conditions would the current high deficit crowd out private expenditure?
- What do you understand by a ‘Green New Deal’? How realistic is such a New Deal and would there be any downsides?
- Is the disagreement between the economists the result of (a) different analysis, (b) different objectives or (c) different interpretation of forecasts of the robustness of the recovery and how markets are likely to respond to alternative policies? Or is it a combination of two of them or all three? Explain your answer.
- Why is the effect of the recession on the supply-side of the economy crucial in determining the sustainability of a demand-led recovery?
On February 14, the Sunday Times published a letter by 20 eminent economists calling on the next government to cut the public-sector deficit more rapidly than that planned in last December’s pre-Budget report.
In order to minimise this risk and support a sustainable recovery, the next government should set out a detailed plan to reduce the structural budget deficit more quickly than set out in the 2009 pre-Budget report.
The exact timing of measures should be sensitive to developments in the economy, particularly the fragility of the recovery. However, in order to be credible, the government’s goal should be to eliminate the structural current budget deficit over the course of a parliament, and there is a compelling case, all else being equal, for the first measures beginning to take effect in the 2010-11 fiscal year.
Then on 18 February the Financial Times published two letters, between them from more than 60 economists, backing Alistair Darling’s policy of delaying cuts until the recovery is firmly established. They openly disagreed with the 20 economists who wrote to the Sunday Times.
… while unemployment is still high, it would be dangerous to reduce the government’s contribution to aggregate demand beyond the cuts already planned for 2010-11 (which amount to 1 per cent of gross domestic product). Further immediate cuts – even supposing they are practicable – would not produce an offsetting increase in private sector aggregate demand, and could easily reduce it. History is littered with examples of premature withdrawal of the government stimulus, from the US in 1937 to Japan in 1997. With people’s livelihoods at stake, a responsible government should avoid reckless actions.
… A sharp shock now would not remove the need for a sustained medium-term programme of deficit reduction. But it would be positively dangerous. If next year the government spent less and saved more than it currently plans, this would not “make a sustainable recovery more likely”. The weight of evidence points in the opposite direction.
So why do such eminent economists have apparently such divergent views on tackling the public-sector deficit? Is there any common ground between them? What does the disagreement imply about the state of macroeconomics? Read the letters and articles and then try answering the questions.

Questions
- To what extent is the disagreement between the two sets of economists largely one of the timing of the cuts?
- Is the disagreement the result of (a) different analysis, (b) different objectives or (c) different interpretation of forecasts of the robustness of the recovery and how markets are likely to respond to alternative policies? Or is it a combination of two of them or all three? Explain your answer.
- How would new classical economists respond to the Keynesian argument that it is necessary to focus on aggregate demand if the economy is to experience a sustained recovery?
- How would Keynesian economists respond to the argument that rapid cuts will reassure markets and allow private-sector recovery to more than compensate for reduced public-sector activity?
- Why is the effect of the recession on the supply-side of the economy crucial in determining the sustainability of a demand-led recovery?
- Distinguish between the cyclical and structural deficits. How would the policies advocated by the two groups of economists impact on the structural deficit?
The following two clips look at John Maynard Keynes’s contribution to macroeconomics and whether his theories have been proved to be correct by the events of the past two years.
“What would John Maynard Keynes make of the financial crisis and the credit crunch?” In the first clip, “Author Peter Clarke, former professor of modern British history at Cambridge University, and the former Conservative chancellor Lord Lamont consider whether Keynes’s ideas were twisted by modern politicians to support their desires to run big spending deficits.”
